1. Alkali Release and Effects on Biomass Thermal Conversion Processes
Sammanfattning : High alkali content is an important feature of biomass, and it has a series of implications for thermal conversion processes. This thesis focuses on the release of alkali during various biomass thermal conversion processes, including biomass pyrolysis, char gasification, co-conversion of different types of biomass, and thermal conversion of biomass mixed with fresh and used bed materials.

2. Numerical modelling of biomass thermochemical conversion and potassium release
Sammanfattning : The use of biomass as a renewable source of energy has been increasing over the past few decades, and biomass is regarded as a promising replacement for fossil fuels. Thermochemical conversion of biomass is a common approach for biomass utilization with a relatively short conversion time. LÄS MER
3. Gasification of biochars: Evolution of pore structure, effects of alkalis and alkali release
Sammanfattning : Renewable energy sources are indispensable to meet the rising demand of energy usage while reducing the negative environmental impact of utilising fossil fuels. Gasification is an efficient technology to convert biogenic waste into valuable gaseous products. LÄS MER
4. The Release, Distribution, and Implications of Alkalis in Chemical Looping Combustion of Biomass
Sammanfattning : Chemical looping combustion (CLC) of biomass is a promising technology for power generation with a potential net negative CO2 footprint. Like other fluidized bed biomass conversion technologies, biomass CLC may be susceptible to alkali-induced agglomeration, fouling, and corrosion. LÄS MER
5. Alkali-containing aerosol particles-release during biomass combustion and ambient air concentrations
Sammanfattning : Air pollution in the form of particles has considerable influence on human health and climate. Atmospheric aerosol particles arise from direct emissions of particles and from the conversion of certain gases to particles in the atmosphere. LÄS MER
